Active clinical trials for "Alzheimer Disease"

Objectives: The purpose of this study was to investigate the effects of high-frequency repetitive Transcranial Magnetic Stimulation (rTMS) in Alzheimer's Disease (AD). Methods: Twenty-seven AD patients aged ≥60 years were included in the study and divided into 3 groups (rTMS, Aerobic Exercise (AE) and control). All groups received pharmacological treatment. rTMS group (n=10) received 20 Hz rTMS treatment on bilateral dorsolateral prefrontal cortex, 5 days a week over 2 weeks, and AE group (n=10) received the moderate-intensity aerobic exercise for 50 min sessions, 5 days a week over 2 weeks. Control group (n=10) was only treated pharmacologically. Neuropsychiatric and behavioral status, cognition, balance, functional mobility, and quality of life, and functional brain changes were evaluated before and after the treatment.

The multiple ascending dose (MAD) design of the study is based on the aim to study safety, tolerability, PK and pharmacodynamics of selected doses of ACD856 in a limited number of healthy volunteers. ACD856 will be administered orally.

This research study is intended to 1) better understand seriously ill adults' and their family care partners' (FCP), particularly for persons living with dementia (PLwD), barriers to accepting community-based palliative care (CBPC); 2) develop an intervention to address barriers; and 3) pilot test whether the intervention has an impact on CBPC uptake. The intervention will consist of 1) a set of informational material describing the benefits of CBPC for the CBPC team to use when presenting CBPC to members of a Medicare Advantage plan and their FCP; and 2) processes for tailoring information delivery so that eligible members and their FCP receive information about CBPC that reflects their individualized risk as identified by the Medicare Advantage program's validated 12-month mortality risk algorithm. The clinical trial portion of the study refers to the pilot test (Aim 3 as described below).

This study will evaluate the safety, tolerability, and potential cognitive benefit of the experimental treatment GRF6019 in subjects with severe Alzheimer's disease.

This Phase II, multicenter, randomized, double-blind, placebo-controlled, parallel-group study will evaluate the clinical efficacy, safety, pharmacokinetics, and pharmacodynamics of semorinemab in patients with moderate AD. The study consists of a screening period, a double-blind treatment period, an optional open-label extension (OLE) period, and a safety follow-up period. There may be up to two study cohorts.

This is a Phase IIa study assessing the safety, tolerability and preliminary efficacy of ORY-2001 in mild to moderate Alzheimer's Disease patients.

This study aims to improve cognition and function in patients with Alzheimer's Disease (AD) by administering the oral antibiotic, Rifaximin. Rifaximin is a virtually non-absorbed antibiotic with the unique properties of lowering blood ammonia levels and altering gut microbiota. It is FDA approved for use in patients with hepatic encephalopathy. Rifaximin lowers blood ammonia by altering fecal flora by blocking bacterial RNA synthesis and also by increasing small bowel glutaminase. The Investigators hypothesize that rifaximin will improve cognition and function in AD patients by lowering blood ammonia and / or lowering circulatory pro-inflammatory cytokines secreted by harmful gut bacteria. The Investigators will enroll up to 10 subjects with probable middle stage Alzheimer's Disease. The subjects will be given rifaximin 550 mg orally twice daily for 3 months after evaluation to ensure they have no contraindications. Physician clinical and safety assessments, adverse events, as well as the ADAS-Cog-11 will be administered at baseline and at the 3 month endpoint and two months after stopping treatment (at month 5). Interim safety checks will occur via phone calls one week after baseline and then every 2 weeks till end point. Serum neuronal biomarkers, ammonia levels and pro-inflammatory and anti-inflammatory compounds will also be measured at those times. Bodily fluids (Stool samples) will also be collected. Because of a small risk of developing C. difficile up to 2 months following the last administration of rifaximin, the subjects will be followed for an additional 2 months after the 3 month treatment ends. Rifaximin is contraindicated in patients with hypersensitivity to rifaximin or rifamycin antimicrobials. Hypersensitivity reactions include exfoliative dermatitis, angioneurotic edema, and anaphylaxis. Clostridium difficile associated diarrhea is a risk whenever a patient is maintained chronically on antibiotics, with complications ranging from mild diarrhea to fatal colitis. Drug resistant bacteria can also result from long term use. There is increased systemic exposure to rifaximin in patients with severe hepatic impairment or in patients who are taking P-glycoprotein inhibitors concomitantly. Regarding use in geriatric patients, there were no reported overall differences in the safety of the drug when used in patients 65 years of age or over, when compared with younger subjects.

To evaluate the superiority of brexpiprazole 1 mg or 2 mg over placebo after a 10-week treatment regimen for agitation associated with dementia of the Alzheimer's type in patients who require medication, and to investigate the safety of brexpiprazole and identify the optimum dose.

The lack of efficacious research-based interventions for sexual and gender minority (SGM) older adults living with Alzheimer's disease and other dementias, combined with the heightened risk of cognitive impairment in this population, presents a significant public health problem. SGM older adults are at elevated risk of social isolation and experience significant barriers to healthcare access. Existing interventions for older adults with dementia have been found to be effective for caregiving dyads. Yet SGM older adults, compared to heterosexuals, are significantly less likely to be married or to have biological family members to support them. A significant proportion of SGM older adults living with dementia have no caregiver or care network. The goal of the proposed research is to design and pilot test the cultural appropriateness, acceptability, and feasibility of an innovative translation of a personalized care network-RDAD (Reducing Disability in Alzheimer's Disease) to support those living with dementia without a family caregiver, directly addressing unique SGM-specific risk factors.

The purpose of this study is to determine if a novel brain stimulation approach using magnetic stimulation (Transcranial Magnetic Stimulation [TMS]) can improve memory and thinking processes in individuals with mild Alzheimer's disease (AD).
